Automating System Shutdown
Automating System Shutdown
Automating system shutdown with a collection of shutdown files helps the operator
bring the system to an orderly halt. The shutdown file sequence reverses the order of
commands in the startup file sequence: applications are shut down first, followed by
the spooler and other system software.
Processes That Represent the System
Console
On NonStop S-series servers, the system console is a pair of windows on a LAN-
connected system console. It is represented by the processes $YMIOP.#CLCI and
$YMIOP.#CNSL.
The home terminal is represented by the $ZHOME process pair. Instead of $ZHOME,
you might want to use the optional NonStop Virtual Hometerm Subsystem (VHS)
product.
For more information, refer to the NonStop S-Series Hardware Installation and
FastPath Guide.
CIIN File
The CIIN file contains a limited set of commands that usually:
•
Start a TACL process pair on the system console for the system console TACL
window ($YMIOP.#CLCI)
The OSM or TSM client software allows you to define primary and backup IP
addresses for the TACL windows. For more information about configuring OSM or
TSM software, refer to the OSM User’s Guide or TSM Configuration Guide.
•
Load all processors that are not currently running or can reload a minimal set of
processors (such as processor 1) to bring up a minimal system.
The CIIN file is initially configured at the factory as $DSMSCM.SYS.CIIN. You do not
need to do anything to establish this file. DSM/SCM automatically copies the CIIN file
from the initial location to each SYSnn you create. For more information, refer to the
NonStop S-Series Hardware Installation and FastPath Guide.
Process Persistence
When the system is started, all processes that are configured to be persistent are
started automatically by the $ZPM persistence manager or by the subsystem manager,
which is started by $ZPM.
To make important system processes such as the Expand manager process or the
Subsystem Control Point (SCP) process start automatically at system load and be
